    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Optical illusion: Look at the center dot for at least 5 seconds. What you should see is that the missing dot becomes light green. Keep staring at the same point for another 10-30 seconds, and you might notice that some pink dots will "disappear". This is due to cone fatigue in your eyes.
